Be it known that I, ROGER W. ANnnEws, a. citizen of the United States, residing at Pittsburgh, in the countylof Allegheny and 5 State of Pennsylvania, have invented certain new and useful Improvements in Steam Purifiers, of which the following is a speciication.l

had to that-patent for further 'information as to details which are njot material'idf'any This invention relates to .improvements in 10 iuid separators, and has for its object the production of means for more perfectly separa-ting-the impurities, particularly liquids, from. various gases. The Iinvention is directed particularly towards 'eliminating all 15 of the li uid from the gas such as oil vapor or steam(loy maintaining the speed of the gas through the-separator at the most desirable rate. A further object is to properly distribute thegas so that it will pass through all portions of the separator atsubstantially the saine rate, and thus the capacity as well astheveii'ectivenessof the'separator will be increased. Other objects of the invention will beapparent. from a consideration of the accompanying, drawings andthe following description thereof.

Ofthe' drawings Fig. l is a transverse sectional view of a steamseparator, which embodies the features of my invention; and 30 Fig. 2 is a. longitudinal sectional view of the separator mounted in a boiler.

Although I have herein illustrated and dclscribed a steam separator as embodying my invention, yet it is to be understood that the invention' is 'applicable'to the separation of huids, -such as the separation'of moisture from steamijor puriiication of vapors or gases. and the'term separator or purifier as used herein is intended to refer to any suitable form of duid separator or vapor purifier wherein impurities such 'as liquid or solid particles are separated from the gas or vapor which it is desired to purify.

As is'. well understood'. it is common, in order'to se arate impurities` such as mois- .tnre from t esteem, to pass the steam, on lits wavkrom the interior ofthe boiler to the steam mains of the system, through a purilier or. separator.Y 'The purifier ordinarily` comprises-some fform of bellies, around or vthrough which the steam must pass, and so arranged. that, while fthe-.steam itself will .pass throu h, yet the impurities such as retained and' pass back The apparatus which I prefer 4her n., illustrate my invention comprises'faacasin 5 in the sides of which-are mountedsL of bailiesv The casing when;l inps 1s mounted withinthe boiler 4 and the 'stianrn-l r passes'through the-baiiies 6 intotheintericr cha'mben' of the purifier;- and,r h'e'ng, Ordin. narily, the steam' passes throughan'outlet 10 out of the boiler ,4 into the steam. main; of the system. As the steam passes, throughthe jf bafiies the moisture therein is stoppedfin .-itsgg flow bythe baffles and it runs downwardl. me into the passageway 8, and thencev thrugiiaaa a pipe' 9 into'the boiler water, or 't oany poin(ti to which it is desired to discharge this li ui have found, however.` that, if the speed o'thesteam through the baiies istoo great, the separation of the moisture froni',tl1e steam will beimpe'rfectas there, is moreel less of a tendency for the moisture, owing to, spattering orv otherwise.. to,l he` carriedalongwffnv with the steam. While the exact speed dwith Awhich the steam passesv thmugh the baiiie's is not very materiahyet' I have'foundrthat. 'f the speedl of some portion of vthe 'steam f90? "1 through ordinary purifiers 'or scparators'fis'f'fFf too great. With the ordinary types of puri-' fiers the passage of the steam'throughthe purifier meets with less resistance as theout# let 10 is approached, hcn'ce,.the steam enter'- ing near the outlet end of the puriier'passes through the bailes at a much higher speed j than that of the steam entering atmo're ref motie points. As a'consequence the'lsteam'. y, .entering near the outlet passes throu h the bailies frequently attoo high a spee and, L at the samev time, the steam' entering at refv t mote points passes through the baies at'. unnecessarily low speeds. Further Aif steps.1 are taken, such as increasing the resistance through the baiies, to reduce the speed near the ontletto a speed which will give complete sepmteniewsrd at remote wie@ utmost 1 isso-lowt-hat'the capacity of the purifier is very greatly'reduced.

Therefore, in order to properly distribute the steam soas t9 Acausait' to" pass throughthe bailles at all'portions ofi the purienat' substantiaily un1form. speeds which.v are suiiciently low to produce'f perfect separa-- tion, oratleast maximum'separation,1 pro.- vide means fr obstructing' the ow more and more as the outlet is approached, ,and I the speed nearthe'outlet without reducing the speed at incre ,remote points materially below the speed near the outlet; Any suit-` able means may be used for'producingsuch aresistance tothe flow of the stear'n.'v In' Athis instance I prefer to provide means lwithin the passageway 7' so arranged that' the,

resistance tolthe flow from this passageway to the outlet increases at la suitable rate as the outlet is'approached. Y

In carrying out this provision I provide a passageway 11. running. longitudinally' within the passageway 7 and connected'with passageway 7 byopenings, the cross section distance above the side walls ,1710i the pasof which decreases gradually as the outlet v1() is approached. f In this instance I provide such openings byraisingthe top plate 13.0f the central passageway- 11: at material ab e manner such' as by bolts 14and collars 15. And I raisethe `rearend ofthetop plate 13 materially higher than the front 'or-- loutlet end so as toprovide 4a wedge shaped passageway or opening 16 between. the cen- .tral chamber `7 andv the passageway 11f through which the steam must pass on its way from the baies to the outletv 10. n Thus by properly adjusting the inclination of the top plate -`13 'I am able to' correspondingly' vary the relative resistance to the flow of the steamfrom the baies into thepassageway 11 and hence to the outlet 10 so as to provide 'a flow of vsubstantially uniform speed through the bailles throughout. the' entire length of the purifier.' And byproperly adjusting the lengths of the collars. 13

this speed may be reduced to any desired amount. i l
